All of a sudden our Sky+ box is asking for a Pin no. for playback of any films we have recorded form the regular Sky movie channels. Any movie that has a certificate, it is asking for. I have tried using the last 4 no.s on my card etc but no go and I cannot get through to Sky support (waited 45 mins on hold then gave up). The regular recorded tv programs are ok and no one in our household has set a pin either on purpose or by mistake. Any ideas anyone?
